Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household products, in particular to a growing chair support and a growing chair. BACKGROUND

[0002] Modern furniture products have higher requirements for the scene adaptation of seats. The growing chair, as a basic design idea, is valued. The function of the growing chair is to meet the use needs of each age stage, from the high feeding period of lactation in the baby period, the safe interaction in the learning to walk period, the rocking chair function in the entertainment period, and even to the general leaning seat for teenagers and later. A single form of seat can no longer meet the whole cycle of care needs. For the growing chair, the current mainstream growing chair on the market generally has basic height adjustment or limited expansion capability (such as a detachable tray), but its design logic still stays at the functional superposition level: the lifting mechanism relies on exposed pins or rotating buckles, which is cumbersome to operate and has the risk of pinching. The expansion components (footrest, guardrail, rocking chair kit, etc.) are temporarily installed through independent accessories (screws, straps), resulting in loose structure and time-consuming disassembly. This "single-point optimization" mode makes the product face the dual bottlenecks of low adjustment efficiency and poor expansion stability when switching between eating, playing, and resting scenes.

[0003] In-depth analysis shows that the fundamental defect of the prior art is the structural lack of scene adaptation capability. On the one hand, the height adjustment mechanism (such as spring pin, threaded rod) is rigidly coupled with the main frame, which cannot provide collaborative adjustment support for the derived needs such as footrest spacing and chair back inclination. On the other hand, the connection of the tray, rocking chair components and other key modules relies on external auxiliary parts, and the system rigidity and operation safety are low. As mentioned above, the so-called "multi-functional" growing chair in the prior art is actually fragmented into several isolated subsystems, which cannot achieve efficient switching between scenes, and it is even more difficult to guarantee the dynamic safety of users in different use states. The prior art fails to adapt to the scene due to its structural defects, and there is a technical defect that cannot meet the needs of various application scenes. This is to be solved. SUMMARY

[0048] The present application provides a growing chair support 1.

[0049] In the embodiments of the present application, as Figures 1 to 10As shown, the growth chair support 1 comprises a seat mechanism 11, a footrest mechanism 12, a first lifting device 13 and a second lifting device 14. The seat mechanism 11 is arranged on top of the footrest mechanism 12. The seat mechanism 11 comprises a seat plate 111, a connecting part 112 and a foot plate 113. The connecting part 112 is provided with a second lifting fixing structure 114 on the side thereof. The footrest mechanism 12 is used for supporting the seat mechanism 11. The footrest mechanism 12 comprises a foot support 121 and a first lifting fixing structure 122 arranged on the side of the foot support 121. The first lifting device 13 is connected to the seat plate 111 through the connecting part 112. The first lifting device 13 is configured to selectively cooperate with or disengage from the first lifting fixing structure 122, so as to adjust the height of the seat mechanism 11. The second lifting device 14 is arranged between the seat plate 111 and / or the foot plate 113 and the connecting part 112. The second lifting device 14 is configured to selectively cooperate with or disengage from the second lifting fixing structure 114, so as to adjust the distance between the seat plate 111 and the foot plate 113. It should be understood that the specific arrangement positions of the first lifting fixing structure 122 and the second lifting fixing structure 114 are important. Preferably, at least part of the first lifting fixing structure 122 and the second lifting fixing structure 114 are arranged inside the connecting part 112 and the foot support 121, respectively. Further, the first lifting fixing structure 122 and the second lifting fixing structure 114 are provided with a rail structure on the side thereof. This design can avoid the first lifting device 13 and the second lifting device 14 from slipping off the first lifting fixing structure 122 and the second lifting fixing structure 114, thereby improving the safety of use.

[0050] It should be noted that some structures in the drawings of the present application, such as the foot plate 113, the chair back 21 and the first connecting groove 16, are labeled in most of the drawings, but this does not limit the scope of the present application. The purpose is to clearly show the structure as much as possible. In addition, there are three main use states in the present application, i.e. the sitting state represented by the growth chair support 1, the dining chair state represented by the growth chair 2 and the rocking chair state. The following description will mainly focus on these three use states. Due to the integration of the built-in lifting device and the three main use states, the present application is suitable for a wide range of user ages and a variety of application scenarios, thereby having the beneficial effect of adapting to multiple application scenarios.

[0051] In some embodiments of the present application, the first lifting device 13 comprises a first shell 131, a shell cover 132 cooperating with the first shell 131, and a first lifting assembly 133, the first shell 131 defining a first accommodating cavity 1311 therein for accommodating the first lifting assembly 133, the first lifting assembly 133 comprising a first button block 1331 and a locking piece 1332 movably arranged in the first accommodating cavity 1311, the first button block 1331 and the locking piece 1332 being in transmission connection, the first shell 131 further comprising a first through hole 1312 arranged towards the first lifting fixing structure 122, the locking piece 1332 being configured to be connected to the first lifting fixing structure 122 after passing through the first through hole 1312 at least partially, so as to prevent the first lifting device 13 from moving relative to the leg support mechanism 12, thereby limiting the seat plate 111, the first button block 1331 being configured to drive the locking piece 1332 to move after being acted upon by an external force, so that the locking piece 1332 is disconnected from the first lifting fixing structure 122, thereby allowing the first lifting device 13 to move relative to the leg support mechanism 12, and the limitation on the seat plate 111 is released. It can be understood that the first lifting device 13 moves within the range preset by the first lifting fixing structure 122, thereby changing the height of the seat plate 111. In the prior art, the first lifting fixing structure 122 has various preset ranges, such as friction sleeve adjustment and multi-stage hole position adjustment. However, considering the cost and safety, the present application shows that the multi-stage hole position adjustment is a preferred embodiment. It should be noted that in this embodiment, the connection part 112 only serves to connect the seat plate 111 and the first lifting device 13, and does not have to be a specific pipe structure as shown in the drawings. In subsequent embodiments of the footboard 113, the connection part 112 needs to be explained as a connection pipe, or at least other similar large components with multi-stage hole positions. Through the preset range of the connection pipe, the seat plate 111 and the footboard 113 can be moved by the second lifting device 14, which will be described in detail later.

[0052] Specifically, the first button block 1331 comprises a pressing part 13311 and a first acting part 13312, the locking piece 1332 comprises a locking part 13321 and a second acting part 13322, the first acting part 13312 and the second acting part 13322 are in transmission connection, the first acting part 13312 is configured to move linearly in the direction of the external force after the pressing part 13311 is acted upon by the external force, and to drive the second acting part 13322 to rotate by contacting the second acting part 13322 in transmission, thereby causing the locking part 13321 to rotate and retract from the first through hole 1312.

[0053] More specifically, in order to enable the first key block 1331 to automatically reset after being subjected to external force, the pressing part 13311 is provided with a first reset component 1333 for resetting the first key block 1331, and the first reset component 1333 is arranged at the opposite side of the pressing part 13311 subjected to external force; the locking sheet 1332 further comprises a stand column 13323, and the stand column 13323 is provided with a second reset component 1334 for resetting the rotation of the locking sheet 1332.

[0054] More specifically, in some preferred embodiments of the present application, the first reset component 1333 adopts a spring, and the second reset component 1334 adopts a torsion spring. Since the first reset component 1333 adopts a linear movement scheme, a spring is directly adopted to facilitate the resetting purpose. Since the second reset component 1334 is a rotation movement scheme, a torsion spring is adopted to facilitate the resetting purpose. In some other embodiments of the present application, the first reset component 1333 and the second reset component 1334 can adopt elastic fibers, rubber, sponge and other components with the same elasticity, so as to replace the materials. The elastic material is part of the prior art, and will not be described here. In specific settings, the elastic material is constructed differently, for example, the first reset component 1333 is provided as a strip, and the second reset component 1334 is provided as an arc.

[0055] In some embodiments of the present application, in order to make the use experience of the seat mechanism 11 more comfortable, the seat mechanism 11 further comprises a footboard 113. In specific applications, the footboard 113 is used to carry the feet of the user. The footboard 113 is connected to the connecting part 112 and arranged below the seat plate 111.

[0056] Specifically, since there are differences in the growth and development of infants and children, it becomes necessary to design a growth chair support 1 that facilitates the adjustment of the distance between the seat plate 111 and the footboard 113. In some embodiments of the present application, the connecting part 112 side is provided with a second lifting fixing structure 114. It should be noted that the connecting part 112 here should be limited to a connecting pipe, or at least other larger components similar to the pipe body that provide a space for the second lifting fixing structure 114. The seat plate 111 and / or the footboard 113 are provided with a second lifting device 14, which is configured to selectively cooperate or disengage with the second lifting fixing structure 114, so as to adjust the distance between the seat plate 111 and the footboard 113.
